Hero revive with gold

[Orcses]

I have an idea but I don't know how to do it. There are two players and I start their gold at 5. The gold represents their amount of revives left. So I was going to do it with a trigger, but I have it so the players can get more gold by doing quests. So now I don't know how to do it with triggers. Should I do it so that when a unit picks up the gold, it adds that number to the variable? A way to go about that would be helpful

Edit: yay I got it so I'm good now:shades:
